Field notes
The matcher asks about tank volume as well as pH and hardness, and offers “I don't know yet” for the water measurements. Its sample output reports 47 matching species. The homepage says its scorecards contain eight key numbers and five beginner warnings; the listed examples include minimum tank volume, group size, pH range, swim zone and temperament.
